Abstract

The invention relates to a landfill method for rapid stabilization of chromium-containing soil and household garbage. The chromium-containing soil, mineralized waste, anaerobic sludge and kitchen garbage are mixed and filled in the land by a certain way, and then the leachate is subjected to continuous reflux; and 1-2 years after filling, the leachate wastewater can reach discharge standards, so as to achieve stabilization of chromium slag and household garbage.

Description

technical field

[0001] The invention relates to a landfill method capable of quickly stabilizing chromium-containing soil and domestic garbage, which involves mixing sludge, chromium-containing soil and domestic garbage for landfill, controlling certain conditions, and realizing the stabilization of the two, which belongs to environmental engineering technology field. Background technique

[0002] Chromium and its compounds are commonly used basic raw materials in metallurgy, metal processing, electroplating, tanning, paint, pigment and other industries. In the production process of the above industries, a large amount of chromium-containing waste gas, waste water and waste residue will be generated, resulting in serious environmental pollution problems.

[0003] On the other hand, how to remediate chromium-containing soil has always been a difficult problem in the environmental protection circle. Although there are many disposal methods, most of them have various probl...
